Vprovided around i the which the sieve Qing which incloses thesieve, and which will iserve to wash `thelumps which remain in jthersieve` after the fine particles of ashes the claims ratenteareb. 1e, 191e.

i cal reticulated'drum 1, preferably made for the mostpart of wire and provided at the -endswith cross bars 2, 3 respectively to receive the shaft l to which said cross bars are made fast in orderfthat the sieve may rotate with the shaft. There is preferably sieve at each end a hoop to stifenthesieve and-receive the ends ofthe'lengthwise wires of the sieve.

`One end'ofthe cylinder is also provided with a head-6 of wire netting. The other end of the 'cylinder is 'provided with :a

hinged cover 7 having an annulariia'nge 8 which shuts ont/side, of the hoop 5 and is rhinged at 9 so that thefsaidcover may be turned back on its hinge to open that: end

` of the cylinder. Both ends" of the shaft 4 areprolongated. y One `ofthe prolongated endspassesthrough a slot'lO in the cover 7 and -the otherprolongated endwpasses out A:through the oppositeheadof the cylinder and is `formed with a crank "handle 11 by y may be rotated. The slot 1() 1n the cover extendsradially outward to the outer vperiphery of the cover so that the" cover may be turned back on its hinge 9-into open position without interference with the `prolongations of the shaft.

4The wire cylinder isV formed with a large opening 12 in oneside through which the combined ashes and coal or clinkers 'which come fromthe rakingS-lofthe furnaceor stove maybe poured intothe sieve. Aslide l cover or gate 13 1s providedwhich isslidable in grooved ways in the longitudinal metal Strips 14, 14, Vsaidymetal strips being doubled over asshownin Fig. 2 to form grooved ways for` thesliding fof the cover ``13 toY open and` close thelsarnel" The said A slide cover is formed with a handle 16` to vmanipulate the slide.V l Y The cylindrical sieve-is journaled in a casing`17`the end walls of whichare formed with vertical slots 18, the bottoms of Said slots forming hearings for the shaft-l1.` Said "slots extend` upward tov thefupper edge of the casing `so `that said Shaft" p with the ysieve ,attached can be` liftedout of the case to removetthe contents `of thelsieve after` the sifting `is completed so that thesieve may l easily be putback intoi'ts bearings after the 'sieve has been emptied ofits contents.

, TheV bottomffof the casing or hopper is provided with n' downwardly tapering funnel* portion 19 terminating in" a cylindrical lowerportion' Which-is a'daptedlto-t into' the top of a suitable cylindrical bucket 21. The inclined sides of thefunnelportion 19 are seated upon the rim 22 of the bucket to support the casing of the sifter duringthe sifting operation and the inclined Walls 19 also direct the ash vportion Which comes out of the sieve down into the bucket 2l.

The bucket 21 is preferably providedfwithy a bail 23 or other suitablehandle Which Will 'be out` of the Way' Awhen the sifter ismounted upontheV bucket and; which is utilized for handlingthebucket after the sitfter is removed therefrom' s'o that the'bucket may be carried to any place for dumping the'contents thereof. y

A dome-shaped cover 2% is' provided for the casing 17, saidcover being hinged at 25 to one side of the casing at its upper edge.

The cover is Aturned back on its hinge as' shown by dotted lines in Fig. 2; to permit the sieve` to be introduced into the casing and'to be removed therefrom and it is" closed during the sifting operation so" as to pre- -vent the dust from coming out into the room Y In order to dampen the Vashes so as to make less dstduring the siftingfand also to wash the contents of the sifterafter the ashes havebeen sifted out of it before' the 4of said cylinder. 'On thet-op of the' dome cover24 there isprovided a curb or tank 28. Inside of the boundaries ofthe curb there is a hole 29 through the cover and opening into the top of the' perforated cylinder 26. The curb is provided With a' cover 30, preferably hinged .at one side as at 31, and having a handle 32 by which the cover may be turned back' on its hinge.

The dome cover 24 is provided' With a handle 33 by Vmeans of which the dome cover may be easily turned back on its hinge. The case 17 is preferably provided Wi'tlrliandles 34 by means of which the case may be' lifted so as to remove it from its seat on" thebucket.V

Normallywhen the device is not in use and When the bucket and sifter are empty Y thejcase 17 of the sifter-Would be mounted uponthe bucket 2121's shown in Fig. 1.

. Wienit is desired to use the device'ithe dome c0ver24twill be turnedvback on its hinge and the cylindrical sieve will' be lturned.,until..,theslide'13- comes to the top.

The slide will thenbermoved so as toun` cover theentrance open1ngl2andthe unsifted` asheslwill be poured into the sieve through said opening and. the slide 13 Will Y then be closed; Tlieldomecover24 Will also then be closed and the cylindrical sprinkler 26 will benlled yivithvvater, the curb 28 allowing s'uiiicient-Water to be put in to more than iill the cylinder 26 and rise in the curb. The cover 30' to the curb will then be closed. Tater will slowly trickle through theaper-V tures 27 and dampen the contents" of the sieve`s0=as`t rreduce the amount of dust that will arise. The crank handle 23 Will then be turned, thus rotating the siei'fefandfthe rotary movementwill canse thefashesto sift throiigh the meshes of! the sieveY and: drop donin through the 'tapered hopper 'portion 19 into thebu`ck'et121. Y p v lifter the *sieve has 'been rotated suiid `cieiitlyYV tocau'se allof theashes andfine'particl'es that vcan `goi throughl the-meshes of the sieve to pass out, the dome ,coverf24f'vvillbe openedandi the sieve will belliftedfout of its bearings a'spermitt'ed'V by its vertical slots. Theclosed' sieve which `novv :contains the solid matter which "is vto be burned again can be used-ars a holder toi carry itto'some place Where the' siftingsare kept or kit 'may be immediately dumped intorafnothrrecep tacle bly 'firstl opening-'the hingedl end `cver 7 so that the' contentswcan'befpoured outv of the end of the `cylindrical sieve.s 0r if desired,l they can bei pou-red therefrom directly into* the stove. *The sieve `Will thenfbeVreplaced in its bearings andl the casel 117 Will belifted 'away from the bucket 21.1 fThe Vashes which were' sifted froml the-slid matter which now areA in the-bucket-'21fcan easily 100 be carried aWay and dumped iny the proper place for ashes. Then the-parts canagain be assembled asl shown inFig. 1 ready for 4thefnerit time of use.
